论文摘要
我们报告了环形有效的非弱势陷阱中非平衡极化凝结的平均场模型，这是由于环形形状的光学诱导的激发式储层而引起的。我们在两个Delta功能有效的壳电位的近似值中求解了线性化的延长GROSS-PITAEVSKII方程，以用于捕获极化的北极星模式的复杂光谱，并计算相应的凝结阈值光泵浦功率。陷阱参数的多维空间中的冷凝水量子数转换的详尽图，包括一系列拓扑电荷增量，与拓扑中的单个环形陷阱案例和可访问的冷凝水状态的范围截然不同。
We report the mean field model of nonequilibrium polariton condensation in annular effective non-Hermitian potential traps, stemming from incoherent optically induced excitonic reservoirs of annular shape. We solve the linearized extended Gross-Pitaevskii equation in the approximation of two delta-function effective shell potentials for complex spectra of trapped polariton modes and calculate corresponding condensation threshold optical pumping powers. The exhaustive map of condensate quantum number transitions in the multi-dimensional space of trap parameters, including a cascade of topological charge increments, is drastically different from the single annular trap case in topology and the range of accessible condensate states.
